The Oberheim SEM V is designed to faithfully reproduce the warm sound and elegant interface of the Synthesizer Expander Module, one of the most iconic analog synthesizers, developed by Oberheim Electronics in 1974.

The SEM V modules were entirely redesigned after the most recent evolutions in TAE, Arturia’s proprietary technology that recreates analog modules after their detailed electronic circuitry. The result of this lengthy project is a faithful virtual instrument that delivers the same acoustic properties as the original.

Oscillators Like all components of the SEM V, the two oscillators were recreated by respecting 100% of the properties of the original circuit. They replicate the exact sawtooth and variable-width pulse waveforms present in the original. On a control level, the SEM V interface also duplicates the behavior of the dual-concentric knobs for coarse and fine-tuning, this last parameter being easily accessible via right-click.

Filter The 12dB/octave multimode filter is one of the most remarkable modules in the SEM. In many ways, it helped define the sonic identity of Oberheim because it shaped a diverse range of sounds that were almost impossible to get on other synthesizers. The SEM V carefully models the four modes of the filter (low-pass, high-pass, notch and band-pass) with attention to detail, meaning that you can either switch to bandpass or sweep through the other three modes by turning the knob clockwise.

ADS Envelopes and Modulations The particular response of the ADS envelopes is accurately reproduced, as well as the VCF Mixer, Modulation knobs and switches, allowing you to nail any of the classic SEM tones.

Extended Functionalities The SEM V adds a few tricks to the original model, that considerably increase the sonic possibilities and allow the demanding musician to push the boundaries of the Oberheim sound a little further:

Keyboard Follow. The intuitive Keyboard follow lets the user draw modulation curves on the fly. You can map up to 6 parameters of your choice, guaranteeing a maximum expression of playing on your MIDI keyboard.

Voice Programmer Inspired by the multi-timbrality of the Oberheim 2, 4 and 8 voice, the Voice Programmer is a powerful module on which you can edit no less than 7 additional virtual SEM voices. Unlike the repetitive manipulations on hardware SEM, the Voice Programmer makes programming a breeze thanks to its ergonomic interface. Whether you want to play spectral pads or complex sequences, this module will allow you to reach amazing sonic results in no time.

Modulation Matrix The SEM V Modulation Matrix offers 8 simultaneous modulations which you can set between 8 different sources and more than 25 destinations.
